Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a waste liquid collection device for a luminescent immunoassay analyzer. Background Technology
[0002] A chemiluminescence immunoassay analyzer is a precision instrument used to detect specific substances in biological samples. It is widely used in hospitals, research institutions and other fields. During the detection process, waste liquid containing biological components is generated. This waste liquid needs to be collected and treated safely and effectively to prevent environmental pollution and biological hazards.
[0003] The application number "202121729333.X" discloses a "waste liquid output device for a fully automated chemiluminescence immunoassay analyzer," which "includes a waste liquid tank, a float plate slidably connected to one side of the inside of the waste liquid tank, a first control switch located on one side of the inside of the waste liquid tank and at the bottom of the float plate, a second control switch located on one side of the inside of the waste liquid tank, and a flexible tube provided on the waste liquid tank, the bottom end of the flexible tube penetrating the waste liquid tank and extending to the bottom of the waste liquid tank. The float plate can reflect the liquid level in the waste liquid tank. When the liquid level reaches a certain height, when the float plate contacts the second control switch, a water pump is energized to extract the waste liquid from the waste liquid tank and discharge it to the outside of the waste liquid tank, eliminating the need for manual emptying, saving time and labor, and avoiding the risk of disease infection from manual emptying."
[0004] However, the above method still has the following drawbacks: the water pump can be powered on by contacting the float plate with the second control switch, and the waste liquid in the waste liquid tank can be extracted, avoiding the risk of (spreading) disease infection from manual dumping. However, it is not convenient to treat the waste liquid, and it is difficult to effectively separate and remove pollutants. If the chemical reagents contained in the waste liquid are not properly treated, they will pose a serious threat to the environment and human health. Utility Model Content

[0037] After the waste liquid and reagents are stirred, the pollutants can be separated from the waste liquid after precipitation. The sedimentation tank 14 can precipitate the pollutants. First, the solenoid valve 902 of the drain assembly 9 is opened to automatically discharge the treated waste liquid. Then, the solenoid valve 1302 of the sewage discharge assembly 13 is opened to automatically discharge the pollutants precipitated inside the sedimentation tank 14. The staff can use the existing solenoid valve controller to control the solenoid valve 902 and the solenoid valve 1302 to avoid human contact.
[0038] When the inside of tank 1 needs to be flushed, the operator opens the butterfly valve 805 and inputs flushing water into the tank 1 through flushing pipe 1 804 and flushing pipe 2 806. The one-way valve 802 prevents the flushing water from reaching the supply pipe 2 803. Then, the butterfly valve 805 is closed, and the cleaning agent is input through the feed pipe 3 and stirred by the impeller 7. Finally, the cleaning agent is discharged through the solenoid valve 2 1302.
